Nine warriors. One oath. One rule they must never break.In a world set in ancient northern Nigeria, nine warriors guard the villages and the great well of Ahdar Wells. They serve no throne and may never love a woman of the villages. For one night before every battle, they light a blue lamp. A veiled woman answers it and leaves before dawn.Karam has kept the oath all his life. Then he's sent to guard a princess who isn't afraid of danger, or of him.Every night he stands outside her door. Every night the oath weighs a little less.What the storm gives, a Warden must hold. What the heart wants, he must leave at the door.But some doors don't stay closed.

Ara’s life changes overnight when she runs into Uche, her former school crush.  What feels like a second chance quickly turns into something far more complicated, as Uche pulls her into a world of wealth and power in a bid to protect her.
